MATRIX FOR USE IN TYPOGRAPHICAL MACHINES.

Specification of Letters Patent.

Patented May 5, 1914.

Original app1ication filed November 15, 1909, Serial No. 528,222. Divided and this application filed May 1,

1912. Serial No. 694,358.

To all whom it may concern:

Be it known that I, CARL HERRMANN CHRISTEL, a subject of the King of Prussia and German Emperor, and residing at Belle called into requisition. The operative po-' sition in a machine equipped with matrices is that adapted to register with the mold. The specification of the second of the above two patents, shows two'face matrices held with their lower faces in the operative position, by a ledge 12 (Figure 3) while they are in and passing through the assembling elevator I, and by a ledge on a socalled blade 72 (Figs. 4 and 13) while they are in the first elevator N. Neither of these ledges underlies the bodies of the matrices they underlie only the cooperating bottom lugs which project to the front from the said bodies. Between the assembling elevator I and the first elevator N, there is the intermediate channel M which has a ledge at functionally the same level therein as the ledges above mentioned. It is on this ledge that the front bottom lugs of the said matrices ride as they pass through the said guide M. These matrices pass through the assembler elevator I, then through the guide M, into the first elevator N and, lastly, out of it, their front bottom lugs rubbing most of the time upon the said ledges. Now, as none of the said ledges underlie the bodies of the matrices, but the front bottom lugs only, all the wear on the matrices due to friction between them and the ledges, falls upon the bottom faces of the said lugs. This wear is very mischievous, because matrlces so worn, will hold their lower face below the operative position, by a distance equal to that wear.

The object of the present invention is to prevent or minimize such wear, by increasing the area of contact between each matrix on the one hand, and a ledge on the other, this increase being in the direction of the width of a ledge, whereby some of the body of each matrix, in addition to its front bottom lug, shall rub over and rest upon the ledge.

The accompanying drawings show improved matrices according to the present invention, together with a part of a linotype machine in which the said matrices are adapted to be used and spacers adapted for operative association with the said matrices. The machine here selected for illustration is the same as that chosen for the illustration of the inventions of the two patents abovementioned, viz :a Mergent'haler line casting machine; neither the said machine nor the spacers, however, constitute any part of the present invention, they, themselves, having been embodied in an application forv Letters Patent, Serial Number 528222, filed November 15th 1909, from which the present one is a divisional application.

In the said -drawings:Fig; 1 is a side elevation of a matrix; Figs. 2 and 3 are vertical sections looking from the right-hand side of the machine; and Figs. 4, 5 and 6 are side elevations of spacers.-

1, 1 are bodies of matrices; 2, their front top lugs, and 3, their rear top lugs; 4, their front bottom lugs, and 5, their rear bottom lugs; 6, the top formative cavities, and 7, the bottom formative cavities for the two faces of the respective character; one of which cavities must register with the mold cavity; 8, a portion of the mold wheel; 9, the mold block fast thereon; 10,the mold cavity; and 11, the first elevator, all as heretofore.

12 is the widened ledge, the extension or extra width of which projects rearward beyond the face 13 and stands, therefore, in a position for some of the body 1 of a matrix (as distinguished from a front lug a of the latter) to rub over and rest upon. Matrices that are required to have their bottom cavities 7 in register with the mold cavity 10, contact with the ledge 12 by their lugs 4 and adjacent portions of the feet of their bodies 1, such portions being of the same area as the extra width of the said ledge, as shown in Figs. 1 and 2. Matrices that are required to have their top cavities 6 in register with the mold cavity 10, hang in the elevator 11 by their lugs 2, 3 engaging on ledges 14, their lugs 4 being under the ledge 12. As any matrix may be required to have its top cavity 6 in register with the mold cavity 10, when the extra width of the ledge 12 would prevent it passing into the elevator 11, by standing in the way of its body 1, each matrix has a notch 15 in its front edge, large enough to clear such extra width. Figs. 2 and 3 show the widened ledge 12 only in connection with the first elevator 11 of the machine. But it is to be understood that it is equally applicable to both the assembling elevator I and to the intermediate channel M. It is also shown as a fixture upon the said elevator. This ledge may, however, be either fixed or movable, as may be required. The spacers used in combination with either the matrices or type dies above mentioned, also have, if their width renders it necessary, notches in their front edges.

Spacers on the principle of the single or of the double wedge, are well known in connection with the justification of the composed line in a typographical composing machine. To enable wedge spacers to justify the composed line, they are, if single, pushed farther through it; and if double, one or both of their wedges is or are pushed farther through it and over the other wedge, both oushings being effected by the movement of tie justifier. But if these wedge spacers should be as wide as the matrices or the type dies, their having notches 15 in their front ec ges, will not suflicesuch notches must, to meet the requirement of the present invention, be extended lengthwise of the wedge that is to be pushed, for a distance not less than the movement of the justifier, in order that that wedge may continue to clear the extra width of the ledge 12. Thus, the spacers used in a Mergenthaler line casting machine are as wide as the matrices used therein, and are also double wedge spacers.

1G and 17 are the two wedges, of different lengths, oppositely inclined, and both slidably connected together, the short wedge 16 I having lugs 18 which engage in slots 19 in the elevator 11, to support; the spacer therein and to hold the wedge 16 stationary while the longer wedge 17 is pushed through the composed line and at the same time over the wedge 16 by the justifier.

20 is the extended notch. This notch may extend for nearly the whole length of the wedge, stopping short of both top and bottom, as shown in Fig. 4; or throughout the joint length of both wedges, as shown in Fig. 6.

It is essential that the matrices and spacers for each line should be securely clamped together at the mold and also that they should be accurately and closely pressed or clamped.

against the mold, in order that no metal may escape between or around the matrices when the pump is operated. The ledge 12 is made to fitthe notch of each matrix and to extend exactly to the bottom of the notch when the matrix is in casting position. When thus proportioned the ledge operates as a part of the clamping devices to press the matrices firmly and uniformly against the mold. The spacers are required to be not greater in width than the distance from the ledge to the plane of the face of the mold in order that they may be pushed up during the justification of the line. On the other hand the width of the spacers should be equal to the width of the bodies of the matrices at the notches 15, that is, their width should be equal to the distance from the bottom of the notch 15 to the opposite side of the matrix. When thus constructed the ledge 12 will press equally upon the spacers and matrices and hold them uniformly against the mold. The ledge 12 therefore serves to sustain the matrices at the proper elevations when presenting them to the mold and also to assist in pressing the matrices and spacers uniformly against the mold to prevent any escape of metal along the inner face of the matrix line.

In cases in which the matrices are provided with more than two superposed formative cavities, it will be necessary to provide the said matrices with more than one notch 15 and this in a manner which is obvious to any expert. For example, matrices with three superposed formative cavities will each require to have two superposed notches 15 above the lower front lug 4-, and the first elevator 11 or its equivalent will require to have two superposed horizontal ledges '12.

Having described my invention, I declare that what 1 claim and desire to secure by Letters Patent is 1. A matrix for a linotype machine of the class described comprising a body having parallel edges, ears projecting from said body beyond the edges thereof, a notch extending inward from one of said edges, and a type impression in the other edge.

2. A matrix for a linotype machine of the In witness whereof I have hereunto set my class described comprising a body having hand in the presence of two Witnesses. parallel edges, upper and lower ears extending outward from said edges, a rectangular CARL HERRMANN GHRISTEL' 5 notch extending inward from one of the par- Witnesses:

allel edges adjacent one of the lower ears, AXEL PERMIN,

and a type impression in the other edge. VALDEMAR OHRISTENSON.
